It is the only area in a conventional power amplifier likely to give trouble in EMC emissions testing [3]. Even if the amplifier is built into a solidly grounded metal case, and the mains transformer ...

Good description. :-) Another option I’ve used is to pick a transformer with dual 120/120 vac primaries, and use one as the primary, and the other as a HV secondary.

An analog amplifier works in analogous fashion, regulating the output stage devices (transistors) to release power from the amplifier’s power supply to the loudspeakers in a manner that exactly mimics ...

The power supply circuit, designed exclusively for the preamplifier, enables a stable power supply unaffected by fluctuations from power demanded by the power amplifier stage. An oversized toroidal ...

Emotiva didn't pull any punches here. They employed a large 850VA toroidal power transformer to ensure the UPA-7 could deliver all of its rated power and then some. The amplifier modules utilize four ...

The Model 5000's build quality feels super-solid; the amp's massive power transformers and internal heat sinks account for much of the weight.
